Letters Patent No. 110,193, dated December 20, 1870.

.. IMPROVEMENT IN APPARATUS FOR PITCHING BARR'ELS.

The Schedule referred to in these Letters Patent and making of the same.

To all lw/tom may concern.-

Beit knownthat I, JAMES W. BRADY, of Baltimore,

, in thecountyof Baltimore and State of Maryland, have invented certain new and useful Improvements in Apparatus for Pitching Barrels; and I do hereby declare the following to be a full,` clear, and-exact description thereof,'reference being had Ato the accompanying drawing forming part of this specification, in which- Figure 1 is aV sectional elevation of my improved apparatus, and.

Figure 2, a front elevation of the same.

Similar letters of reference indicate corresponding parts in the several figures of the drawing.

The means adopted by brewers and others for pitching 'beer-casks, barrels, die., consist, essentially, in

placing a quantity of pitch within the barrel, and subjecting the same, together with the'interior of, the barrel, to such a degree of heat as will liquefy' the staves.

lhc liqucfaction and distribution of the pitch was first accomplished by heated irons; but, as this method is laborious and, slow, certain improvements were devised by which the barrels were heated, and the pitch liquefied and distributed by the action of a hot blast thrown into the barrels containing the pitch.

These improvements are a great advance upon the -rst crude method of employing heated irons, but are objectionable in one respect, viz., the necessity of placingthe pitch in the barrels by hand beforefthe application of the hot blast.l 'lo avoid this ditliculty is the principal object of my invention; and to this end- It consists, primarily, in forcing melted pitch into barrels, casks, dsc., by the action of a hot blast, both entering the barrels together.

IIt consists7 secondly, inthe construction and combination of devices by which this result is attained.

In the drawing- A is an upright furnace, composed of metal, or

other suitable material, mounted upon legs, VB, andv vprovided with a grate, C, and cover, D.

'lhe upper portion of the cover is constructed in the form'of a kettle, and its under surface forms the top or crown of the fire-pot.' It is adapted to lit upon the furnace by a rebatedjoint, to prevent lateral displacement, and is secured in place by means of hooks, c, engaging with pins or staples, f, axed to or cast upon the sides of the furnace, as shown.

The entrance tothe furnace is;` effected .through a door, G; in the lower portion of the cover D, the inncr'surface of such door being inclined to correspond with the under surface of the cover.

pores of the heatedrThe door is also constructed with flanges, 1t, let into corresponding recesses in the outer surface of the cover, to form a tight joint,'and is held in place by acurved bar, I, notched in its lower edge near each end, to fit over hooks, J, affixed to the cover upon each side of thedoor.

K is a pipe communicating directly with the fur- ,nace through the cover D, and passing vertically through the kettle to the outside of the cover. This pipe-is attached to or forms a part of`- the perforated nozzle L, and through it the hot blast is driven from the furnace into the barrel to be pitched, the nozzle beinginserted in the bung-hole of the latter.

M is a pipe entering the kettle through the side of put in motion, and the cock O in the pipe N turned,

to allow the melted pitch to flow freely to the nozzle, the quantity of such ow being, of course, regulated by the cock.

The-action of the blower drives a hot blast from the furnace, through the` pipe K and nozzle L, into the barrel, which blast encounters the melted pitch as the latter escapes from the pipe N and scatters it uniformly overthe interior of the barrel.

flhehot blast from the nozzle, in addition to distributingthe pitch, heats the inner sui-fece of the barrel, and prepares the latter to receive the proper coating of. pitch.

If desired, the discharge end 4of the pipe N may terminate in the nozzle, so that the melted pitch shall he forced into the barrel with the hot blast, through the pcrforations in thc nozzle.

The cover D may be lifted o ff the furnace by means of a dcrrick, being provided with ears, I), to receive the derrich-chains or ropes. l

The nozzle L is connected to the pipe K in the following manucr:

Upon the end of the pipe K is firmly secured a plate,.Q, having beveled flanges upon its side and bottom edges; and upon the proximate end of the nozzle Lis a plate, R, having its side edges beveled to correspond with the bevel of the flanges upon the plate Q, and with a straight ange across its top.

The two are united by slipping the plate `It between the anges of the plate Q, the top flange ofthe former resting upon the upper edge of the latter, as shown in fig. 1.

This construction forms a. perfectly tight joint, and,

at the same time, permits the ready separation of the pipe and nozzle.

A similar joint is provided in the pipe M, so that the outer end of the same can beV removed with the nozzle from the pitch-kettle. If preferred, the pipe K and nozzle may be made in one piece, as also the pipe M, and attachedto the kettle in any convenient manner, the object being to to pitch the interior of the same,fsnbstantially as described.

3. In an apparatus for pitching barrels, casks, 85e., a. furnace having its cover constructed to form the pitch-kettle,substantially as described, for the`pur. pose specified.

4 In combination with the furnace and kettle, Vthe pitch-pipe M and the hot blast-pipe and nozzle, substantially as described, for the purpose specified.

5. In combination with the hot blast-nozzle; L, the pitch-pipe M, substantiallyas described, for the purpose specified.

6. The anged plates Q R, constructed as described, to connect the sections of pipe, substantially as set forth, for the purpose specified. 7. The door -G, constructed as described, and applied to the furnaceV and its cover, in the manner set forth,for the purpose specified.
